Four men have been sentenced to decades in jail for their roles in a "sophisticated" drug importation that saw 1.2 tonnes of methamphetamine — with an estimated worth of up to $1.1 billion dollars — smuggled into Western Australia.
The sentences come five-and-a-half years after the drugs were seized in the WA port city of Geraldton in what was, at the time, the nation's largest ever meth bust.
